pkg-config on MSYS

[Tollef Fog Heen]

* "lode leroy" 

| I have used the following modifications to get pkg-config working on MSYS
| MSYS uses C:/some/path instead of C:\some\path
| This patch makes it work on both msys and windows.

Something along those lines is included in the just-released 0.20.
Can you please verify?
